Trends in affordability of tobacco products before and after the transition to GST in India.

OBJECTIVE: To estimate the trends in affordability of bidis, cigarettes and smokeless tobacco (SLT) in India and examine the impact of transition from the earlier indirect taxation system to the new goods and services tax (GST) on the affordability.
METHODS: Retail price data and per-capita gross domestic product data were used to examine the trends in affordability of cigarettes, bidis and SLT from 2007-2008 to 2018-2019. Relative income price defined as the share of real per-capita income required to purchase a given quantity of a product was used to measure affordability. Changes in affordability were decomposed to disaggregate the effects of real prices or income changes.
FINDINGS: On average, cigarettes, bidis and SLT have become increasingly affordable over the past 10 years. Bidis were found to be nine times more affordable than cigarettes. The GST has accentuated the increase in the affordability of cigarettes and SLT, and did not significantly alter the high affordability of bidis. In general, states with high (low) value-added tax rates during the pre-GST period experienced increases (decreases) in tobacco products' affordability after GST.
CONCLUSION: Bidis continue to be highly affordable while the affordability of cigarettes and SLT increased mainly due to lack of any tax changes after GST and the growth in per-capita income. To effectively reduce affordability, significant increase in either the excise taxes and/or the compensation cess-a temporary duty in addition to GST-is warranted. Compensation cess should also be applied on bidis to address the huge tobacco use problem in India. © Author(s) (or their employer(s)) 2021. No commercial re-use. See rights and permissions.
